Claims
- 1. A stand-alone combination ice maker and beverage dispenser, comprising
- a housing,
- an ice making device having a series of compartments in which water is adapted to be frozen to form ice cubes, and an evaporator in the housing for freezing water in the compartments to form ice therein,
- a beverage cooling and dispensing system comprising a tank in the housing for holding a liquid, an evaporator in the tank for chilling said liquid, at least one beverage conduit positioned in the tank for exposure to chilled liquid to cool beverage flowing through the conduit, and at least one dispensing head connected to said at least one beverage conduit for dispensing beverage supplied via said beverage conduit to said dispensing head,
- a single compressor in the housing,
- refrigerant conduit means in the housing connecting said single compressor and the evaporators of said ice maker and said beverage cooling and dispensing system for flow of refrigerant from the compressor through said evaporators and then back to said compressor to effect a refrigeration cycle,
- a hot gas bypass line and regulator associated with said refrigerant conduit means for directing some of the gas flowing from an outlet of the compressor to an inlet of the compressor in the event the supply of refrigerant from the evaporators to the inlet of the compressor drops below a predetermined amount, and
- a desuperheating thermal expansion valve operable to introduce a liquid into said hot gas bypass line to cool gas flowing therethrough.
- 2. A stand-alone combination ice maker and beverage dispenser as set forth in claim 1 further comprising a thermal expansion valve associated with each evaporator for regulating the flow of refrigerant via said refrigerant conduit means to the evaporator.
- 3. A stand-alone combination ice maker and beverage dispenser as set forth in claim 1 further comprising a sensor in said tank adjacent the evaporator for sensing the build-up of ice on the evaporator and for generating a signal in the event such build-up exceeds a predetermined amount, and valve means operable in response to said signal for shutting off the flow of refrigerant to said evaporator.
- 4. A stand-alone combination ice maker and beverage dispenser, comprising
- a housing,
- an ice making device having a series of compartments in which water is adapted to be frozen to form ice cubes, and an evaporator in the housing for freezing water in the compartments to form ice therein,
- a beverage cooling and dispensing system comprising a tank in the housing for holding a liquid, an evaporator in the tank for chilling said liquid, at least one beverage conduit positioned in the tank for exposure to chilled liquid to cool beverage flowing through the conduit, and at least one dispensing head connected to said at least one beverage conduit for dispensing beverage supplied via said beverage conduit to said dispensing head,
- a single compressor in the housing,
- refrigerant conduit means in the housing connecting said single compressor and the evaporators of said ice maker and said beverage cooling and dispensing system for flow of refrigerant from the compressor through said evaporators and then back to said compressor to effect a refrigeration cycle, and
- a sensor in said tank adjacent the evaporator sensing the build-up of ice on the evaporator and generating a signal in the event such build-up exceeds a predetermined amount, and valve means which operates solely in response to said signal to shut off the flow of refrigerant to said evaporator.
